[Elecraft] KPA100 J8 standoffs

[jon howe]

Hi:
Everything went together flush, square and true, if I do say so myself.
I should have mentioned that I can get the standoff just barely threaded 
into the retaining nut, by a quarter turn or less.  Not really enough to 
ensure that it stays fastened.  It's the thickness of the plastic flange 
that is the main culprit.
Do you know the manufacturer and part no of that connector?  I would 
like to have a look at a drawing of it.
